Title: Vernier voltage-to-digital converter.
Inventor: FRICK ROGER L
IPC: G01R27/26
Filed: 1990-08-30
Abstract: A voltage-to-digital converter comprising a storage circuit for providing a storage capacitance with a plurality of selectable magnitudes. The storage circuit provides a charge output representative of applied voltage input signals and the selected capacitive magnitude. A charge accumulation circuit is coupled to the charge output. The total charge accumulated is proportional to the integral of the amount of charge discharged from the storage circuit. The charge accumulation circuit provides a balance output representative of a comparison of the accumulated charge and a reference charge. A control circuit is coupled to the balance output for providing feedback signals as functions of the balance output for periodically charging and discharging the storage capacitance whereby a first sequence of charge packets is provided on the charge output for driving the accumulation of charge toward the reference within a first set of limits when a first capacitive magnitude is selected in the storage circuit and whereby a second sequence of charge packets is provided on the charge output for driving the accumulation of charge toward the reference charge within a second set of limits when a second capacitive magnitude is selected in the storage circuit. A calculation circuit is coupled to the feedback circuit for counting the number of charged packets generated in a measurement cycle. An output circuit provides an output indicative of the voltage input signals as a function of the number of packets counted.

A ready-to-serve meal selected by the operator is removed in a deep-frozen state from the corresponding tubular magazine (11) by means of a removal device provided on the underside of the cooling space (12) and placed on the cooking tray (39) situated in the feeding position. The slide front (33) subsequently closes, the cooking tray (39) moving automatically back into the cooking space (41) of the oven (31). After expiry of the necessary defrost and cooking time, the hot ready-to-serve meal is conveyed directly from the oven (31) into the dispensing space (42) by means of the movable cooking tray (39). <IMAGE>

Abstract: Apparatus for inspecting the thickness of a container wall, such as a glass or plastic container wall including a plurality of elongated sensors disposed in a linear array in spaced end to end relationship. The containers are urged into intimate contact with the sensor elements and are rotated thereover. The containers are moved from sensing element to sensing element with each element inspecting a portion of the circumference. Oscillators convert the change in capacitance to a corresponding voltage which, in turn, in a processor is converted to an actual thickness reading which is compared with desired predetermined thickness levels. By segmenting the sensors in this manner, a plurality of containers may be inspected simultaneously with a processor combining the individual segments of sensor readings so as to reconstruct the complete thickness evaluation of the container. A corresponding method is provided.

Abstract: La présente invention se rapporte à des méthodes et à un appareil pour effectuer la diagraphie sonique à basse fréquence de trous de sondage au moyen d'ondes en "tube" utilisant des mesures de fréquences discrètes. Un transducteur de source (16) émet de l'énergie sonique à un emplacement dans le trou de sondage (14) à au moins une fréquence discrète, ce qui provoque la propagation d'ondes "en tube" dans le trou de sondage; l'énergie sonique des ondes "en tube" est reçue à des emplacements de réception multiples dans le trou, ces emplacements étant distants les uns des autres ainsi que de l'emplacement du transducteur de source; et, à chaque emplacement de réception, la réponse complexe de pression (l'amplitude de la phase, ou des parties réelles et imaginaires) d'un récepteur (20-30) à l'énergie sonique des ondes "en tube" reçues est déterminée par rapport à une référence de phase. La réponse complexe de pression detectée peut être analysée pour déterminer la vélocité de phase des ondes en tube dans le trou de sondage en fonction de la fréquence, pour déterminer l'affaiblissement desdites ondes dans le trou en fonction de la fréquence et/ou pour déterminer l'affaiblissement et l'amplitude en fonction de la fréquence. En outre, les coefficients de réfraction d'ondes près de cassures, de limites de lit etc., peuvent être calculés. Les données d'ondes "en tube" sont utiles à la corrélation de perméabilité, l'évaluation de cassures, les études de rigidité de la roche et dans d'autres applications.
